I INTRODUCTION
Rural Infrastructure is the key to inclusive growth by
connecting the rural hinterlands and enabling the rollout of many additional socio-economic sciences.
With a growing rural road network of the country and
with ambitious rural road development plans, there is
a great need for the roads sector to build a sustainable
and environment- friendly road infrastructure for low
volume rural roads.
It has been observed that it would be economical to
use industrial wastes in the construction of low
volume rural roads. The estimates prepared by
Ministry of Power as well as Planning Commissions
up to the year 2031-32 indicate that the coal
requirement and generation of fly ash during the year
2031-32 would be around 1800 million tonnes and900 million tonnes respectively.
On one hand, the management of such a large volume
of fly ash and mitigation of its likely impact on
environment as well as demand on land for
deposition/storage is a mammoth task, on the other
hand the fly ash has been proved to be a useful
material for a number of applications with potential
to conserve valuable minerals, substitute materials
inter-alia protection of environment by decreased
mining activity and reducing CO2 generation being
produced during a process of production of materials
that can be substituted by Fly Ash. Thus, there lies a
challenge to convert the threat to an opportunity.Fly Ash has been proved to be a useful material for
many applications. The policy framework and
national strategy can make it possible to utilize all fly
ashes in gainful manner. It would mitigate the
environmental threat, generate employment and
industrial wealth, conserve mineral resources and
provide sustainable construction.
